The patch adds the DT binding documentation for Samsung Exynos5 SoC series imaging subsystem (FIMC-IS). Signed-off-by: Arun Kumar K<arun.kk@xxxxxxxxxxx> Reviewed-by: Sylwester Nawrocki<s.nawrocki@xxxxxxxxxxx>
Can I have a DT binding maintainer Ack for this binding ? I'd like to queue this patch for 3.13 once the merge window has closed.
